摘要： A radiographic image capturing apparatus includes a housing and a radiation detector accommodated in the housing. The radiation detector includes a scintillator for converting radiation into visible light and photodiodes for converting the visible light into electric charges. If it is assumed that a temperature-dependent rate of change in sensitivity of the scintillator with respect to the radiation is represented by A [%/K] and a temperature-dependent rate of change in sensitivity of the photodiodes with respect to visible light is represented by B [%/K], a scintillator and photodiodes are selected having temperature-dependent rates of change A and B that satisfy the following inequality (1): −0.35 [%/K]

摘要： In a radiation image reading method for reading image signals corresponding to radiation image information from a radiation solid-state detector in which the radiation image information is recorded by irradiation of a recording electromagnetic wave, correction of an offset and a gain in the image signals, which are attributable to a dark current of the radiation solid-state detector, is performed more accurately and easily. A correction pixel region, in which a light-shielding member 6 is provided so as to be adjacent to respective read pixels, and a correcting means 25 corrects an image signal corresponding to the read pixel based on a correction region signal corresponding to the correction pixel region adjacent to the read pixel.

摘要： An image information reading apparatus that can obtain high quality images without an effect of noise and a photographing condition or the like is realized even in the case where a low-bit A/D converter is used. The apparatus comprises control means for switching between pre-reading to main reading, characteristic determination means for determining, by analyzing an electric signal obtained by the pre-reading, a normalization processing characteristic used in normalization processing on an electric signal obtained by the main reading, and normalization processing means for carrying out the normalization processing on the electric signal in the main reading according to the determined normalization processing characteristic. The characteristic determination means analyzes image data by using a cumulative histogram of pre-reading data, and determines the normalization processing characteristic so that an image represented by the image data has adequate density and contrast.

A two-dimensional image read-out device is located on the other side of the object. The two-dimensional image read-out device comprises a charge accumulating section for accumulating latent image charges, which carry image information. An anisotropic fluorescent material screen is located between the object and the two-dimensional image read-out device, and an operation for recording and reading out an image of an object is performed in this state. Problems with regard to deterioration of image sharpness are thus capable of being reduced.
